Study summary

There is very limited research examining isokinetic parameters and activity level in patients with amputation.. Therefore, the aims of this study were to illustrate isokinetic measurements including strength and proprioception and to analyze the correlation between those isokinetic parameters and activity level and to predict amputee mobility score. It is hypothesized that muscle strength and proprioception were associated with activity level and could be used to estimate amputee mobility scale score in patients with amputation.

Read the detailed description

Isokinetic measurements are used in the rehabilitation of amputee patients and to evaluate the effectiveness of rehabilitation. The parameters that are frequently looked at in these measurements are isokinetic muscle strength and proprioception.

What researchers measure

Primary outcomes

  1. Isokinetic muscle strength

    Muscle strength will be assessed for flexion and extension of the hip using a computer-assisted isokinetic system (CYBEX) in the isokinetic performance laboratory

    Time frame: Through study completion, an average of 1 month

  2. Isokinetic proprioception

    Isokinetic proprioception will be measured with the CYBEX device. The hip joint is chosen because the most proximal level amputation will be the above-knee level

    Time frame: Through study completion, an average of 1 month

  3. Amputee mobility predictor

    Amputee mobility predictor (AMP) is one of the performance-based outcome measures commonly used prior to prosthetic fitting and predict function following prosthetic prescription.The AMP is a 21-item tool for predicting the level of ambulation by assessing static and dynamic balance, transfers, and gait. With this scale, unilateral patients can be evaluated with or without prosthesis. However, activity level of bilateral amputees can only be predicted if they have prostheses. In this study, AMP evaluation of all patients will be performed by a physiotherapist with 10 years of experience in amputee rehabilitation, blinded to other clinical information.

    Time frame: Through study completion, an average of 1 month
